Valve is an important mechanical base part, is the control part of the fluid conveying system, with opening and closing function, regulation function, throttling function and other functions and effects.

1, the valve should be stored in a dry and ventilated room, and both ends of the channel should be blocked. 2, long-term storage valve should be regularly checked, remove dirt, and apply anti-rust oil on the processing surface.

Ball valves are divided into: floating ball valves, fixed ball valves, track ball valves, V-shaped ball valves, three-way ball valves, stainless steel ball valves, cast steel ball valves, forged steel ball valves, ash discharge ball valves, anti-sulfur ball valves, pneumatic ball valves, electric ball valves, sleeve ball valves, welded ball valves.

First, wear-resistant; Because the spool of the hard sealed ball valve is alloy steel spray welding, The sealing ring is alloy steel surfacing welding, so the hard sealed ball valve will not produce too much wear when switching. (It has a hardness factor of 65-70) : Second, good sealing performance; Because the seal of the hard seal ball valve is manually ground, it can be used until the spool is completely matched with the seal ring. So his sealing performance is reliable.
